I bought some red mushroom on a rock from the lfs. It came with these brown polyps and i have no clue what they r. Could someone tell what ive got and how to care for it?

Can you get a better focus? Hope they are not a heavy aiptasia infestation.

Could be yellow polythoas polyps that have been deprived of adequate lighting.

[Monster00101]

they get lots of light. I tried for a long time my camera sucks. They r only on tjat one rock but they r spreading on that rock.

[Monster00101]

i searched both of those and i dosent look like either. they r really small and hve a black dot in the middle of each one.

You need to post a better pic

[Monster00101]

id love to but its not gonna happen this camera sucks.

[Monster00101]

when i touch them with something they close up if that helps at all. its basicly a stem with a little ball of fur on the end and a black dot in the center.

Ok then, maybe some kind of anthelia.

[Monster00101]

that could b it at a really young stage. sorry i cant get a better pic. any suggestion i will search and c if i can id it.

[Monster00101]

it also spreads and grows like a weed

[Chiefsurfer]

they do look too brown to be this, BUT maybe a pineapple sponge?

[Monster00101]

no i dont think thats it these have a really small stem. thay almost look like a star polyp only they r about 1 cm big and they have about 20 - 30 small hairs on the top. it looks like they r branching i really dont know how else to descibe them.

[Toddrtrex]

Almost look like Hydriods ( sp ), but I hope that I am wrong. Very difficult to get rid of.

[Monster00101]

I think thats it. It is the darker ones on the right.

[Monster00101]

is this a problem and should i get rid of it. it is only on the small rock i got. Should i cut the mushrooms of get rid of it?

[Monster00101]

its not the bigger ons on the right

[Monster00101]

heres another pic that looks like it

[VacavilleFC3S]

definitely hydroids

[Monster00101]

how big of a problem r they?

[Monster00101]

shuld i get them out right away?

[Chiefsurfer]

hydroids should not be a problem. I mean they ARE problematic, However, they cannot really survive for long in our tanks. Hydroids are basically jellyfish. There are 3 stages. 1, egg, 2, "stalk" version that you have, then free-floating jellyfish. Usually once they hit the jellyfish stage they all die and cannot reproduce.

That last photo looks like brown, green star polyps. Don't know if there is a brown star polyp. If it is a star polyp, then they may be a nuissance, and can grow very quickly.
